Definitions

  • the invention relates to a roll winding device, especially for a slitter with at least a support device by at least one support roller is formed with its axis in the transverse direction is arranged in a machine frame that to the a stator arrangement at both axial ends of the support roller having at least one traverse in Transversely connected.
  • the invention is in the context of a Roll winding device for winding a paper web described. But it is in the same way also with other material webs, such as cardboard, foils Metal or plastic, or textile materials, can be used.
  • the paper web are wound into salable rolls. If necessary, if it is in a larger size Width has been produced, even on the right one Be brought wide. This slitting is done in many cases just before winding up.
  • a support device In order to support the winding rolls during winding, a support device is provided.
  • This support device can be formed, for example, by a changing bed be formed by two or more carrier rollers is. For the sake of simplicity, all rollers the support device referred to here as support rollers.
  • the stand arrangements are provided at the axial ends.
  • the vibration stiffness and the stability of the entire machine frame to ensure, are usually Trusses inserted between the stand arrangements and firmly connected to them. If you look that way has built a stable framework, the required Functions integrated.
  • the greatest loads on the machine frame occur in Area of the support roller bearing. For example, there Vibrations initiated due to unbalance of the support rollers that cannot be completely eliminated result.
  • the stand arrangements can be placed in this position but don't connect directly because of appropriate space is taken up by the support rollers. The further the crossbeams are removed from the support rollers the larger and more stable the trusses have to be and the stand arrangements are dimensioned.
  • the invention has for its object a roll winding device specify a particularly compact and inexpensive construction.
  • This task is done with a roll winding device of the type mentioned in that the at least a traverse near the carrier roller Stator assemblies connects, designed as a sealing box which is arranged below a changing bed and has such high mechanical stability that it increases the rigidity of the frame as when installing an additional traverse.
  • the sealing box is in the immediate vicinity of the support rollers arranged. This position is due to its function conditionally.
  • the winding roll usually does not have to be held the winding roll on the winding core. Accordingly takes the force with which the winding roller on the support rollers of the changing bed rests with increasing diameter to. This increases the contact pressure and so the winding hardness.
  • a weight relief of the winding roll with the help of a Air cushion causes.
  • compressed air is fed into the changing bed. In order to the compressed air cannot escape, it is necessary to seal the changing bed. Accordingly the sealing box is not a large distance from the support rollers exhibit. You can now use the sealing box for an additional Take advantage of the function.
  • EP 0 631 956 A2 shows a double carrier roller winder with two carrier rollers and a sealing box located underneath that opens Rails transverse to the axial direction of the two support rollers can be moved to fill a gap between the Carrier rollers and the sealing box to create.
  • DE 195 38 973 A1 shows a carrier roller winding machine for winding webs with two support rollers, the together a changing bed to take one from the web formed role.
  • a changing bed to take one from the web formed role.
  • On the underside of the winding bed a blow box is arranged, the one Compressed air connection.
  • the blow box has two Walls with sealing elements against the support rollers issue.
  • DE 196 24 716 A1 shows another winding machine for Winding up a running paper web in which a Sealing box or blow box below the two support rollers is arranged.
  • the sealing box can also be simple only be designed as a sealing wall. Independent of its design is the sealing box around an axis pivotable, which is parallel to the axes of the Carrier rolls extends.
  • US 5 478 026 A shows a winding machine with two support rollers, on which there is a sealing box from below.
  • the Sealing box is attached to a lever, which by a Axis is pivotable, the side next to the two Carrier rollers is arranged.
  • EP 0 769 464 A2 shows a blow box with a connecting wall, the side walls of the blow box with each other combines. When the web of material falls off the material web no longer in the blow box, but is caught by the connecting wall, creating a enables quick and easy disposal of waste becomes.
  • the sealing box advantageously has a section modulus W x of at least 10 6 mm 3 per meter length. With this section modulus it is sufficiently stable to increase the rigidity of the frame.
  • the increase in rigidity is as great as when installing an additional crossbar. This does not only apply to the static condition, where the addition of a further cross member leads to a further increase in the rigidity of the machine frame. It is of particular importance in the present case that the vibration rigidity during operation is drastically improved by the immediate vicinity of the sealing box as a traverse to the support roller bearings.
  • the sealing box advantageously carries a guide roller. Such a traverse can even be more than assign a function. You can use it to add more trusses save to reduce costs and save installation space.
  • a second truss arrangement as a knife traverse be formed on the at least one slitting knife arrangement arranged movably in the transverse direction is.
  • two trusses namely one for the upper knife and one for the lower knife. Compared to another traverse but you can look at the two knife traverses together.
  • the knife traverse is advantageously adjacent to the sealing box arranged, the knife traverse is hollow and over several air lines distributed in the transverse direction communicates with the changing bed.
  • the knife traverse for example the knife traverse for the top knife, another function. It directs the air that is needed to build one Pressure pad under the winding roll is necessary the desired position in the cross direction of the machine, thus serves to distribute the role relief required compressed air.
  • connection is preferably made via the sealing box. This also gives the air lines an additional one Task. On the one hand, they take over the air transport between the upper knife traverse and the Sealing box. They also stiffen the machine frame in the longitudinal direction because it is another mechanical Connection between trusses in the longitudinal direction create.
  • a roll winding device 1 is used to make a paper web 2 or another material web to form a winding roll 3 wind up.
  • the winding roll 3 lies here on a changing bed 4, which is formed by two Carrier rollers 5, 6.
  • the support rollers 5, 6 are arranged in a machine frame with their axes 7, 8 in the transverse direction.
  • the machine frame points to the two axial Ends of the support rollers 5, 6 each have a stand arrangement 9, 10 on, dashed in Fig. 1 for reasons of clarity is drawn.
  • the stand arrangements 9, 10 are in the transverse direction several trusses connected to each other.
  • a sealing box 11 is arranged below the changing bed, the one on the top is an air outlet 12, through which the changing bed 4 compressed air can be fed to a compressed air cushion in the changing bed 4 to relieve the weight of the winding roll 3.
  • the sealing box 11 has such a high mechanical stability on that he used to brace the machine frame can be used.
  • the rigidity of the machine frame noticeably increased. This does not only apply to the static condition. Here comes a traverse added.
  • the sealing box crossbeam has a stronger influence but in operation. Since they are in close proximity the support rollers and thus also the support roller bearings is arranged, it conveys one to the machine frame improved vibration resistance.
  • the sealing box 11 carries on its underside a guide roller 12, which over a guide roller bearing block 13 is connected to the sealing box 11.
  • the Sealing box 11 thus performs three functions, namely once to seal the changing bed 4 from below to second, a guide roller 12 for deflecting the paper web 2 to wear and thirdly to stiffen the machine frame and stabilize.
  • Trusses arranged, also for bracing serve, namely an upper knife traverse 14 and a lower knife traverse 15.
  • the upper knife traverse enters Upper knife 16, which acts as a counter knife
  • the lower knife 17 cooperates on the lower knife traverse 15, to cut the paper web lengthways.
  • upper blade 16 and lower knife 17 are on their respective trusses 14, 15 slidable in the transverse direction to different Being able to cut web widths.
  • top knife-bottom knife combinations arranged on the two knife traverses 14, 15 are.
  • the upper cross beam 14 is hollow. It stands with one Compressed air connection 18 in connection. Furthermore, it is Via a plurality of air lines 19 with the sealing box 11 connected.
  • the upper knife traverse 14 is sufficient arranged close to the sealing box 11 so that the volume the hollow upper knife traverse 14 in addition to Distribution of the necessary for the role relief Can use compressed air.
  • the distribution of the compressed air takes place via the air lines distributed in the transverse direction 19, which also take on several tasks can. On the one hand, they provide resistance to air down, so that pressure losses can be kept small. They also increase due to the longitudinal connection of the sealing box with the upper knife traverse 14 Rigidity of the machine frame in the longitudinal direction.
